Book excerpt: This report evaluates twenty-two ablative-material samples as nozzle sections of a storable-propellant (nitrogen textroxide and a 50-50 percent blend of unsymmetrical dimethylhydrazine with hydrazine) rocket engine to determine general trends among the material variables and to enable comparison of such trends with those observed from similar tests with a hydrogen-oxygen rocket engine reported in NASA TN D-3258.

Available in PDF, EPUB and Kindle. Book excerpt: Seven different ablative materials have been tested behind Thiokol TOMAHAWK rocket motors. The maximum erosion, erosion patterns, and the mass loss of the samples have been determined from these tests. In addition, time-dependent temperature profiles were measured in four of the test samples during firing. From these data, local ablation rates for the materials were determined. (Author).

This book was released on 1990 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Chinese translation discusses the effects of the structure of organic silicon resins (R/Si and Me/Ph molecule chain forms and comonomer structures) on the thermal stability of materials and ablative properties. Opting for the use of special composite techniques and precise formulation designs, it is possible to compound resins with structures that are linear and branched. They have small weight losses under heat. The char yield ratios are high. The charring layers have great strength, and anti-scouring properties are good. Using endothermic chemical reactions that occur at high temperatures between fillers in order to design materials for formulation, it is possible to effectively lower the cold wall temperature, improving ablative properties. Keywords: Solid propellant rocket motors; Coatings; China. (edc).

Available in PDF, EPUB and Kindle. Book excerpt: New chemical compositions and physical constructions of ablative materials were exposed in three rocket motor combustion-gas environments to determine the potential usefulness of these materials for hyperenvironmental conditions associated with current and future solid and liquid propellant motors. These gas environments were: (1) the exhaust from a high-temperature Aeronutronic solid propellant rocket motor simulator, a nitrogen tetroxide (N2O4)-50 percent hydrazine and 50 percent unsymmetrical dimethylyhydrazine (50-50) liquid propellant environment, and a chlorine trifluoride (CTF)-hydrazine (N2H4) liquid propellant environment. Material erosion and thermal insulation characteristics of the research nozzles were evaluated by comparisons of chamber pressure versus time data, erosion and resin degradation rates, and visual photographic data. Eight nozzle specimens, comprising test series 1, were exposed to the exhaust environment of a storable liquid propellant rocket motor utilizing N2O4/50-50 at a chamber pressure of 700 psia. Twenty-five nozzle specimens (comprising test series 2) were exposed to the exhaust environment of a simulated solid propellant at a chamber pressure of 500 psia; flame temperature was 5800 F and the propellant was highly aluminized. Eight nozzle specimens, comprising test series 3, were exposed to the exhaust environment of another storable liquid propellant rocket motor utilizing CTF/N2H4 at a chamber pressure of 500 psia.

Available in PDF, EPUB and Kindle. Book excerpt: New chemical compositions and physical constructions of ablative materials were exposed to several rocket motor combustion gas environments to determine the potential usefulness of these materials for hyperenvironmental conditions associated with current and future solid and liquid propellant motors. These gas environments were (1) chlorine trifluoride (CTF) and hydrazine (N2H4), (2) nitrogen tetroxide (N2O4) and 50 percent hydrazine/50 percent unsymmetrical dimethlhydrazine (50-50) at three distinct conditions of chamber pressure and restart requirements, and (3) the exhaust from a high temperature solid propellant rocket motor simulator. Material erosion and thermal insulation characteristics of the research nozzles were evaluated by comparisons of chamber pressure versus time data, erosion and resin degradation rates, and visual photographic data. Test results from the four liquid propellant series indicated that the specified nominal test conditions were met, and enabled valid material evaluation. Test results and specimen evaluations also indicated that the solid propellant simulator provided the specified exhaust environment with the required repeatable test screening characteristics to enable valid material evaluation.
